The heart pumps the blood, which carries all the vital materials which help our bodies function and removes the waste products that we do not need.
The heart works as a pump moving blood around in our bodies to nourish every cell. Used blood is drawn from the body by the right half of the heart, and then sent to the lungs to be reoxygenated. Blood that has been reoxygenated by the lungs is drawn into the left side of the heart and then pumped into the blood stream. It is the atria that draw the blood from the lungs and body, and the ventricles that pump it to the lungs and body.
